Johanna is a former Hunger Games winner who becomes a rival to Katniss (Jennifer Lawrence).

One thing Malone doesn't need to do is read the Hunger Games novels—she's already done that.

"I read the whole series over a weekend when I had a wisdom tooth out," she said. "I was in bed looking for something to read and my little sister recommended it like a year and a half ago, so she was like, 'You have to read it! You have to read it!' And so I'm glad I finally did and I loved it."
